Evaporative Cooling Vests

Evaporative cooling vests activate with a quick soak in water: no ice packs, no freezer, no batteries. As the water evaporates, the vest pulls heat from your body for hours of lightweight relief. Shop HyperKewl, AlphaCool, and Ergodyne Chill-Its evaporative vests for landscaping, riding, hiking, and outdoor work.

Evaporative Cooling Vest Guide

Evaporative vests are the simplest and most affordable way to stay cool outdoors. Soak the vest for one to two minutes, wring it out, and wear it over a base layer; evaporation does the rest for three to eight hours.

How Water-Activated Cooling Works

Special polymer fibers hold water inside the vest while keeping the surface dry to the touch. As that water evaporates, it carries body heat with it, the same mechanism that makes sweat effective, but without soaking your clothes.

Best Conditions for Evaporative Vests

Evaporation works fastest in dry air with a breeze, which makes these vests outstanding for the Southwest, motorcycling, and mowing. In very humid climates, an ice vest or PCM vest will outperform them.

Care and Reactivation

Re-soak whenever cooling fades, hang dry between uses, and machine wash occasionally to keep the polymer fresh. A well-kept evaporative vest lasts for seasons.
